Grasscycling

The natural recycling of grass is called "grasscycling". Grasscycling means leaving grass clippings on your lawn after you have finished mowing it. All grass cut with any type of lawn mowers can be used to grasscycle.

When grass clippings start to break down, the nutrients in the grass go back into the soil. This provides free fertilizer to the grass and produces healthy, green lawns. The clippings protect the soil from the hot sun, lower the amount of water your lawn needs and reduces moisture loss. Grasscycling saves time, reduces waste and leads to deeper and healthier roots for your grass. It helps your lawn fight diseases, dry periods and insects.

Tips for cutting grass

  • Cut your grass often. During the spring and early summer you should cut your grass every four to five days. When growth is slower in the late summer and fall you can cut your grass about once per week.
  • Don't cut grass more than one third of its height. No more than 2.5 cm (or one in) should be cut at any one time. If the grass is long, cut off a little bit and then lower the blade and cut off a little bit more rather cutting it all off at once.
  • Make sure your lawnmower blade is sharp.
  • Keep the blade height of your mower at about 6 to 7.5 cm (or 2 ½ to 3 in).
  • Grasscycling works best when the grass is dry. Cutting wet grass or taking too much off at one time can cause grass clumping. If you get a bit of clumping, try mowing the area again from a different direction to break up the clumps.
  • Leaves take longer to break down than grass clippings. You can rake and collect your leaves and put them in a paper yard waste bag for collection. Leaves can also be used as mulch in other parts of your garden. 
  • Grass clippings are  great for your backyard composter. Don't add too many at once because they can become smelly. Allow them to dry in the sun and then add them into your composter in thin layers.

Grasscycling

  • Grasscycling does not cause 'thatch'. Thatch is a tight layer of stems and roots that is found between the growing grass and the soil surface. Thatch is not caused by the blade clippings from grasscycling.
  • Grasscycling does not spread lawn disease. Watering, fertilization and mower blade sharpness affect lawn disease more than grasscycling.
  • Grass clippings provide food for worms. Worms are healthy for your lawn and naturally aerate your soil.
  • Grasscycling should not leave ugly looking grass clippings on your lawn. Grass clippings can not be seen if your lawn is cut properly. Most people who grasscycle find that their clippings disappear within three days after cutting their lawn.
  • Leaving grass clippings on your lawn does not make the grass turn brown. Grass clippings add nutrients back into the soil to help make your lawn healthy and green.
